BBC Radio 5 live Formula 1 analystThe 'power cycle' is a reboot of Stoffel Vandoorne's dashboard. It is always very worrying when you see a car coming in so early for an unexpected stop.

Lewis Hamilton's latest lap is a 1:28.3.
"1:28 is the target," he is told. "Not possible," is the reply.
He's making what looks a comfortable race so far sound distinctly uncomfortable.

Oh I say no significant change in positions further down the grid, but I failed to spot Lance Stroll's superb leap from dead last to 14th! Great start by the teenager.
Meanwhile, Daniel Ricciardo is told to "get stuck in". He's a lap down on the field.

Lewis Hamilton has suddenly found a bit extra and a new fastest lap of 1:28.786 sees him pull 1.3 seconds clear of Sebastian Vettel.

Sebastian Vettel is powering away from Valtteri Bottas and it is looking increasingly likely that it is going to be a race between Vettel and Lewis Hamilton out in front.
Hamilton may be leading, but he's not completly happy. "Struggling or grip," he reports.
No significant change in positions further down the field.

BBC Radio 5 live Formula 1 analystGreat to see Daniel Ricciardo rejoining this race. It is hopeless for him in terms of getting a finish and points, but he will be able to put on a show and get in some valuable miles for his team. Superb work from the Red Bull pit crew.

UNEXPECTED RED BULL GOOD NEWS KLAXON.

Sebastian Vettel may have failed to beat Lewis Hamilton at the first corner but he has chucked a lasso around the Mercedes. The gap stands at half a second, Vettel keeping Hamilton in his sights.

BBC Radio 5 live Formula 1 analystAbsolutely inch-perfect start from Lewis Hamilton. It actually left Sebastian Vettel with work to do to stay with him and protect second spot.
